How can I calculate the I2C_TIMINGR value for STM32L496. I 'll be running I2C system clk with 80 MHz, what are timing register values or psc, scldel, sdadel, sclh, scll values at baud rate of 10 KHz, 100 KHz, 400 KHz, 500 KHz and 1 MHz?

What is a solution of this problem?

STM32F7 and I2S CODEC (CS43L22)

I'm working on a new PCB design based on ST32F746 Discovery schematics.I want to change the CODEC to a cheaper CS43L22 DAC.Can someone help me make the correct connections to the DAC (MCLK, SCLK, SDIN, LRCK) ?An F7 schematic with this DAC would be gr...

Wrong code creation with STM32CubeMX V. 5.0 for STM32H743 and FreeRTOS

I am working on a project with several STM32H743 processors, TouchGFX and FreeRTOS active. The board with the LCD and TouchGFX is already working, but is not yet completely finished.Now I converted the project to work with the latest release of STM32...

STM32F413-DISCO, How can i ru MEMS example

Hi, i have STM32F413-DISCO, this board can do this:"The demonstration firmware uses the MEMS motion sensor to blink the four LEDs according to the motion direction and speed. Connecting the board to a PC with a second USB 'type A to micro-B' cable co...

Resolved! Typo inside the STM32F429 datasheet?

Hi. Believe to have found a typo inside the STM32F429 datasheet (document DocID024030 Rev 10). Studying the use of the STM32F429NI DISC1 Kit and the use of the onboard TFT display. The source code is noting that the CPU is configured into AF14 (alter...

HardFault_Handler in writing 64bit to Flash

I'm using a Stm32f429VI, and I try to write in 64bit mode to the flash.The system goes every time to HardFault_Handler.In 32bit mode I have no problems.I think there is a bug in FLASH_Program_DoubleWord() function ( instm32f4xx_it.c) : the functi...

How to increase SPI data size of STM32F107 to 24 bit ?

I'm working on STM32F107 microcontroller standard library and interfacing external ADC through SPI.In SPI configuration , there are two data size, 8 bit and 16 bit as in below lines - #define SPI_DataSize_16b ((uint16_t)0x0800)#define SPI_Data...

STM32L432KC internal reference

I am working with STM32L432KC in range VDD and VDDA 1.8-3.6V.I have read the reference manual. It doesn't say anything about how to apply the internal reference 1.2V. as a reference of ADC and DAC?
